Operation Agreement was a ground and amphibious operation carried out by British, Rhodesian and New Zealand forces on Axis-held Tobruk from 13 to 14 September 1942, during the Second World War. A Special Interrogation Group party, fluent in German, took part in missions behind enemy lines. Diversionary actions extended to Benghazi, Jalo oasis and Barce. The Tobruk raid was an Allied disaster; the British lost several hundred men killed and captured, one cruiser, two destroyers, six motor torpedo boats and dozens of small amphibious craft.
